EDA 1200 System Overview

Figure 18 Traffic Mapping Schemes (continued)

The following scenarios are illustrated:

1. Traffic mapping between one line and one Service VLAN. This traffic

mapping applies to ADSL, VDSL2 and Fiber/Cat5.

2. Traffic mapping between one PVC and one Service VLAN. This traffic

mapping only applies to ADSL.

3. Traffic mapping where multiple PVCs share the same Service VLAN (PVC

bundling). In practice this is mapping is created using multiple EDA 1200

services. Downstream traffic distribution is based on p-bit distribution

between the PVCs. This traffic mapping only applies to ADSL. For more

information please refer to Section 3.1.2.2 on page 26.

4. Traffic mapping between two Ethertypes and two Service VLANs according

to the Ethertype (PPP or IP) of each frame. This traffic mapping only

applies to ADSL (EDN312 only).

5. Traffic mapping from one PVC, based on End User VLAN ID to two Service

VLANs.
